地处干旱、寒冷、多风的晋西北右玉县于1966年自内蒙引种箭叶红豆草(即普通红豆草Onobrychis sativa Lam),经多年观察,认为该草具有抗旱耐寒、草质优良、适口性好、再生力强、产草量高、耐瘠薄等特点,是蓄水保土、改良土壤、发展畜牧业的优良牧草。 一、生物学特性 箭叶红豆草在当地条件下的生育生理习性及其与外界环境条件的关系,可概述如下:
Located in the northwest of northwestern Shanxi Province, Youyu County, arid, frigid and windy area, introduced the arrow-leaf safed sativa (Onobrychis sativa Lam) from Inner Mongolia in 1966. After years of observation, the grass is considered to be drought-resistant and hardy, with good grass quality and palatability Good sex, strong regeneration, high yield, resistance to infertility, etc. It is a good forage for soil and water conservation, soil improvement and livestock husbandry development. First, the biological characteristics of arrowroot grass in the local conditions of reproductive physiology and its relationship with the external environmental conditions can be summarized as follows:
